Patent CA-2391869-A1 (CA)
Title: Tool and system for aligning and applying fastener to implanted anchor
Inventor: COURNOYER JOHN
IPC: A61B17/88
Filed: 2002-06-27
Abstract: A fastener cartridge installs clamping fasteners, e.g., a set screw and a lock nut, to fix a linking rod or cable in the head of an anchor assembly. The cartridge carries one or more fasteners, or pairs of inner and outer fasteners, and applies them onto the anchor head without cross-threading. A separate holder mechanism aligns and guides the cartridge with a centering body into which the fastener cartridge fits. One cartridge has a box wrench that externally grips and turns the nut, and a central shaft coaxial with the box wrench that positions and rotates a clamp screw in coordination with the nut. Preferably, these are configured, by springs, detents or offset positioning surfaces, to install the inner lock screw coaxially with but ahead of the outer nut to fix a linking member anchor assemblies prior to fitting, e.g., compressions and distractions of the spine and final tightening. The holder mechanism has a distal jaw that grips the anchor head and positions the centering body on-axis, aligning it to avoid cross-threading the fasteners. The holder may have an elongated handle projecting to a side of the centering body for manipulating the holder in a surgical wound, or the holder may have a coaxially disposed and/or telescopically interfitted handle. The handle also actuates a jaw to grip the anchor head and center the assembly. Fastener cartridges may be manually gripped or turned with a wrench remote from the wound. A floating assembly enhances alignment of threads and coordination of fasteners.

Title: Cyclone dust collecting apparatus for a vacuum cleaner
Inventor: OH JANG-KEUN
IPC: A47L9/16
Filed: 2002-08-07
Abstract: A cyclone dust collecting apparatus for a vacuum cleaner for easy removal of contaminants from a grill assembly. The cyclone dust collecting apparatus has a cyclone body for forming a vortex flow of contaminant-laden air that is drawn in through the air inflow port. The cyclone body includes a first connection pipe connected to an extension pipe adjacent to a suction port of the vacuum cleaner, a second connection pipe connected to the extension pipe adjacent to a body of the vacuum cleaner. An air inflow port is interconnected with the first connection pipe, and an air outflow port is interconnected with the second connection pipe.     A dust receptacle is removably connected to the cyclone body for receiving contaminants separated from the air by the vortex. A grill assembly is disposed at the air outflow port of the cyclone body, and is has a plurality of longitudinal slots formed in an outer circumference of the grill body at a constant interval from each other to form a passage for leading air toward the air outflow port. The grill assembly prevents a reverse flow of the contaminants collected in the dust receptacle through the air outflow port of the cyclone body. A contaminant removing member is. movable upwardly and downwardly along the outer circumference surface of the grill body to remove contaminants that are attached to and around the respective longitudinal slots of the grill assembly. A wire has one end connected to the contaminant removing member. A winding member is positioned inside the cyclone body, and the other end of the wire is wound on this reel. A rotary knob connected to the winding member through a shaft, and is positioned outside the cyclone body. A resilient member is disposed between the contaminant removing member and an inner bottom surface of the grill body for resiliently biasing the contaminant removing member downwardly.

Filed: 2001-01-19
Abstract: L'invention concerne l'isolation de données dans un système de communications à ligne électrique. Bien que l'alimentation électrique de plusieurs abonnés puisse être distribuée à partir d'un transformateur de distribution commun, il est souhaitable d'isoler leurs lignes de dérivation les unes des autres lorsqu'on les utilise pour communiquer des données en plus de distribuer de l'électricité. L'isolation des lignes de dérivation est mise en place de manière centralisée au niveau du transformateur de distribution, ou de manière distribuée au niveau de chaque local d'abonné. Ces mises en oeuvre sont effectuées à l'aide de filtres passe-bas (qui laissent passer l'électricité mais bloquent les données) et de routeurs de communication à ligne électrique ou de répéteurs de communication à ligne électrique.
